feat: add Nostr VPN, FIPS, Routstr apps with status UIs

Add three new marketplace apps:
- Routstr (v0.4.3): Decentralized AI inference proxy with Cashu payments
- Nostr VPN (v0.3.4): Mesh VPN with Nostr signaling + WireGuard tunnels
- FIPS (v0.1.0): Self-organizing encrypted mesh network

Includes status UI dashboards for headless apps (nostr-vpn-ui, fips-ui)
with usage instructions, node identity display, and container logs.
Nostr identity injected via env vars for all three apps.
